Description of triangle mesh collision data necessary for cooking physics data.
struct FTriMeshCollisionData
uint32:  1
bDeformableMesh
If mesh is deformable, we don't clean it, so that vertex layout does not change and it can be updated
uint32:  1
bDisableActiveEdgePrecompute
Turn off ActiveEdgePrecompute (This makes cooking faster, but will slow contact generation)
uint32:  1
bFastCook
Prioritize cooking speed over runtime speed
uint32:  1
bFlipNormals
Does the mesh require its normals flipped (see PxMeshFlag)
TArray<FTriInd...
Indices
Array of indices defining the ordering of triangles in the mesh
TArray< uint16 ...
MaterialIndices
Array of optional material indices (must equal num triangles)
TArray<TArray<...
UVs
Optional UV co-ordinates (each array must be zero of equal num vertices)
TArray< FVector...
Vertices
Array of vertices included in the triangle mesh
